AI Technical Summary

Technical Problem

Current treatments for diseases such as infections, tumors, allergies, and menopausal symptoms lack effective agents that can promote the balanced production of IL-10 and IL-12 cytokines, and also address intestinal health and skin conditions.

Method used

The use of novel lactic acid bacteria from weeping cherry trees (Lacticaseibacillus paracasei strain shidare) that promote IgA, IL-10, IL-12, and equol production, enhance intestinal immunity, and improve skin health by promoting collagen and hyaluronic acid synthesis.

Benefits of technology

The lactic acid bacteria enhance intestinal function, improve bowel movements, alleviate symptoms like incomplete evacuation and PMS, and improve skin moisture and elasticity by regulating immune response and promoting equol production.

Abstract

The present invention pertains to a new lactic acid bacterium Lacticaseibacillus paracasei strain Shidare (accession number: NITE BP -04138). The lactic acid bacterium can be used for various health promotion applications, and specifically exhibits a wide variety of effects such as promotion of production of IgA, IL -10, IL -12, and serotonin, normalization of stool shape, improvement of bowel movement, improvement of stool-remaining feeling, regulation of intestinal environment, immunoregulation action, equol production promotion, and collagen gene and hyaluronic acid gene expression promotion.
